2 Peter 1:19 calls the prophetic word more sure (bebaioteron) — a lamp shining in a dark place that the faithful do well to heed. Jeremiah 18:7-10 makes prophecy explicitly conditional: if Yahweh declares destruction against a nation and that nation repents, he will relent; if he declares blessing and that nation does evil, he will withdraw the blessing. 2 Peter treats prophecy as fixed and reliable; Jeremiah treats it as contingent on human response. The two passages disagree on whether prophetic announcements are predictions of fixed outcomes or conditional warnings.
People have answered this in several ways; GEBible presents them as equal peers.
We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:

We have the more sure word of prophecy; and you do well that you heed it, as to a lamp shining in a dark place, until the day dawns, and the morning star arises in your hearts:
[At what] instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy [it]; If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them. And [at what] instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant [it]; If it do evil in my sight, that it obey not my voice, then I will repent of the good, wherewith I said I would benefit them.

At the instant I speak concerning a nation, and concerning a kingdom, to pluck up and to break down and to destroy it; if that nation, concerning which I have spoken, turns from their evil, I will repent of the evil that I thought to do to them. At the instant I speak concerning a nation, and concerning a kingdom, to build and to plant it; if they do that which is evil in my sight, that they not obey my voice, then I will repent of the good with which I said I would benefit them.
Examining the tension
What follows is one scholar’s way of reading this disagreement — a critical-historical view that often concludes the texts genuinely disagree. It draws on the peer-reviewed sources listed below and stands as one position among the answers above, presented for transparency, not as GEBible’s position.
How critical scholarship weighs this: Leans toward a genuine contradiction
This summarizes where critical scholarship tends to land on this tension — a report on the field’s center of gravity, not GEBible’s own ruling.
The tension is real but it operates at a slightly different level than the bare proof-texts suggest, and it pays to separate the two referents. 2 Peter 1:19 is making a Christological claim. The author has just invoked the transfiguration (1:16-18) — "we were eyewitnesses of his majesty" — and then says "we have the prophetic word made more sure" (bebaioteron echomen ton prophētikon logon), a lamp shining in a dark place until the day dawns and the morning star (phōsphoros) rises. Whether bebaioteron means "more sure" than the heavenly voice or "made more reliable" by its fulfillment, the referent is the prophetic witness that points to Christ and the parousia — promise-prophecy, oriented toward a fixed divine future. Jeremiah 18:7-10, embedded in the potter-and-clay oracle, is making a fundamentally different claim about how prophetic announcement functions in the moral economy of nations: it is responsive, not predictive. If Yahweh declares uprooting against a nation and that nation turns from its evil, he "relents" (the niphal of nacham) of the disaster; if he declares building and planting and that nation does evil, he relents of the good. Announcement, human response, divine adjustment.
This conditional model is woven through the Deuteronomistic and prophetic traditions. It is the logic Jonah exploits when he complains in 4:2 that he fled to Tarshish precisely because he knew Yahweh to be "gracious and merciful, slow to anger, abounding in steadfast love, and relenting (nacham) from disaster" — a direct citation of the divine self-revelation in Exodus 34:6-7. It is the logic of Amos 7:1-6, where the prophet's intercession twice moves Yahweh to "relent" of announced judgment ("the LORD relented concerning this; 'It shall not be,' said the LORD"). It is the theology of the Chronicler's Manasseh and of the deferral granted to Hezekiah and to Ahab. Walter Kaiser's harmonization — distinguishing unconditional prophecies (the messianic and new-covenant promises) from conditional ones (oracles of judgment against nations) — is therefore not an ad hoc dodge; it tracks a real distinction in the texts, and it lowers the temperature considerably, because 2 Peter's bebaioteros is precisely about the promise-stream while Jeremiah 18 is precisely about the judgment-stream. To that extent the two passages are not a flat yes/no on "is prophecy sure."
What the harmonization cannot dissolve is that the Hebrew Bible disagrees with itself about whether Yahweh relents at all. Against the relenting texts stand two emphatic denials. Numbers 23:19: "God is not a man (ʾish), that he should lie, nor a son of man, that he should change his mind (nacham); has he said, and will he not do it?" And 1 Samuel 15:29: "the Glory of Israel will not lie or relent (nacham), for he is not a man, that he should relent" — a verse that sits, with some irony, in the same chapter where the narrator twice says Yahweh did relent / was sorry that he had made Saul king (15:11, 15:35), using the same verb. The canon thus preserves two prophetic anthropologies side by side: one in which divine announcement is contingent and responsive (Jer 18; Jonah; Amos 7; Exod 32:14), and one in which it is fixed and irreversible (Num 23:19; 1 Sam 15:29; and the later apocalyptic trajectory toward sealed, determined ends). 2 Peter, working within the fixed-promise stream, calls prophecy "more sure"; Jeremiah, within the conditional-oracle stream, makes it contingent on repentance. The apologists are right that the conflict is not a clean contradiction once the referents are sorted; they are wrong to imply that the biblical view of prophecy is monolithic.
Where the critical reading lands: partially harmonizable by distinguishing promise from threat, but the underlying disagreement over whether Yahweh relents is internal to the Hebrew Bible and not eliminable.
